Why would I override init method in a subclass, in the real world

I understand why you would add a new init method to a subclass if you added new properties. But why would you simply override the init method of a base class. Is it just if you want to change what happens in the base init?

Hi Matt,

Overriding the initialiser in the subclass can be useful for as you said to add new stored properties, but also to change the way certain stored properties are initialised as another example.

Overriding the designated initialiser does not affect the base class. The base class is initialised by calling super.init.

I hope this help out a little and I'm sure you'll discover new examples down the line.

All the best,

Mitch
